Method for object localization using visual images with reference coordinates
There is provided a method of localizing an object comprising projecting an object located on an object plane and a reference point corresponding thereto on a virtual viewable plane and an actual camera plane; estimating coordinates of the reference point; and prescribing a relationship between a location of the object and the coordinates of the reference point.
1. A method of localizing an object, the method comprising:
projecting an object located on an object plane and a reference point corresponding to the object on a virtual viewable plane and an actual camera plane by using a plurality of sensors, wherein the respective planes support zooming and panning of imaging devices;
estimating coordinates of the reference point;
determining a relationship between a location of the object and the coordinates of the reference point, wherein when the location of the object is identical to a location of the reference point, the location of the reference point is determined as the location of the object; and
mutually compensating a difference in localization between the object projected by the plurality of sensors and the reference point,
wherein the plurality of sensors are selected based on a pan factor of each of the plurality of sensors.
2. The method of claim 1 , wherein the virtual viewable plane is parallel to the object plane.
3. The method of claim 1 , wherein sensors whose difference between absolute values of the pan factors is “0” are selected as the plurality of sensors.
4. The method of claim 1 , which is performed one time.
5. The method of claim 1 , which is performed iteratively.
